Rootless containers as self-hosted runners (osc26)

Cloud runners and LLM APIs each run their own billing meter. Use both together and you are billed twice. This talk shows how we use self-hosted openSUSE containers for large codebases, and how we re-used it to eliminate that overlap. We walk through our Linux kernel testing pipeline: cache management, cross-architecture builds, checkpatch per-commit, and more. Then, we explore how we get the most of LLMs by running them inside the same container. Using pi.dev as the agent harness, we can swap the model, and tune the system prompt for one-shot requests. The agent runs after the top-level pipeline completes, with CI annotations (warnings and errors), being part of the prompt. The agent is instructed to assess the issues, and validate its claims by rebuilding and testing. As the output, it generates git patches, and summarizes the session into a structured review summary.
